I will include the TireRack package of 4 Dunlap SP Winter Sport tires mounted on Sport Edition A7 wheels. Balanced, with TPM and BMW logo center caps. used one winter for 5,000 miles. These are the recommended non-staggered winter setup: 18" 235/40.

No body damage, no accidents, cosmetically about 95% showroom.
(the 5% = one inch of road rash on driver side rear wheel, outside edges of front spoiler have minor scrapes, and the inevitable few dings on driver side door.)

Not much more to say...driven reasonably by non smoking 50 y.o. male. never tracked.
